Re: [h-e-w] not urgent: change frame size by function

[Richard M. Heiberger]

Add these to your .emacs

(defun mfp-20+2 ()
  "Place emacs frame in upper right hand corner."
  (interactive)
  (modify-frame-parameters (selected-frame)
                           (list '(top + -20) '(left - +2))))

(defun resize-frame ()
  "Resize current frame to 81 65"
  (interactive)
  (set-frame-size (selected-frame) 81 65)
  (mfp)
)
(fset 'mfp 'mfp-20+2)

(global-set-key [C-f11] 'resize-frame)
(if window-system (resize-frame))
(global-set-key [C-f12] 'mfp)
(if window-system (mfp))



Since you are using R, you will probably want to load ESS (Emacs Speaks 
Statistics)
to give you modes for the S language (S-Plus and R) and for the R process and 
for
R transcripts of previous sessions.
